Calcium parameters

Is a calcium reading of 520 too high? or is that optimum?

Yes that is too high and here is an article for you to read that will explain where all parameters should be: Reef Aquarium Water Parameters by Randy Holmes-Farley - Reefkeeping.com

i just started using a doser and i set it to the lowest settings. Before i installed the doser it was at 420 which was perfect but it would fluctuate to 380. I added the doser and kalk to maintain consistency but i checked it last night and my readings were 520. So i programmed the doser this morning to dose every 2 hours instead of one.
